CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority of Taiwanese Patent Application No. 102147751, filed on Dec. 23, 2013.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a bracket, and more particularly to a curtain bracket that can hang a curtain assembly on a frame of a window or door.

2. Description of the Related Art

FIGS. 1 and 2 illustrate a conventional curtain bracket 13 which is used in pairs for hanging a curtain assembly 11 on a frame 12 of a window or door. The curtain assembly 11 includes a horizontally extending headrail 111, and a curtain 112 connected to and hung downwardly from the headrail 111.

The curtain bracket 13 includes an elongated base 131, a clamping plate 132 fixed to a lower side of the base 131, a threaded rod 133 rotatably disposed between the base 131 and the clamping plate 132, and a movable clamping seat 134. The clamping plate 132 has a downwardly extending fixed clamping wall 135. The movable clamping seat 134 has a movable clamping wall 136 spacedly parallel to the fixed clamping wall 135, a threaded hole 137 formed in an upper portion of the movable clamping wall 136 for extension of the threaded rod 133 rotatably therethrough, and two abutment walls 139 (only one is shown in FIG. 2) perpendicularly extending from the movable clamping wall 136 away from the fixed clamping wall 135.

During assembly, two screws 14 (only one is shown in FIG. 2) are used to mount the headrail 111 to the movable clamping wall 136 at two opposite sides thereof, after which the curtain bracket 13 is hung on a top end of the frame 12. Subsequently, a tool, such as a screwdriver, is used to rotate the threaded rod 133 so as to move the movable clamping wall 134 toward the fixed clamping wall 135. As a result, the curtain bracket 13 is clamped to the top end of the frame 12.

However, to adjust a clamping space between the fixed clamping wall 135 and the movable clamping wall 134 of the conventional curtain bracket 13, a tool must be used to rotate the threaded rod 133 so as to move the movable clamping wall 134 toward or away from the fixed clamping wall 135. The effect of making an adjustment is thus slow. Furthermore, during assembly, the headrail 111 of the curtain assembly 11 must first be connected to the movable clamping wall 136 using the screws 14, after which the curtain bracket 13 together with the curtain assembly 11 is hung on the top end of the frame 12. Finally, the clamping space between the fixed clamping wall 135 and the movable clamping wall 134 is adjusted to clamp the curtain bracket 13 on the top end of the frame 12. Hence, the conventional curtain bracket 13 not only cannot provide good support for the headrail 111, but also is inconvenient to use.

The movable clamping wall 51 has a movable clamping surface 511 facing the stationary clamping surface 422. The frame-clamping space 23 is located between the stationary and movable clamping surfaces 422, 511.

In this embodiment, the locking mechanism 24 has a first locking surface 436 formed on the elastic plate portion 437 and facing the receiving groove 434, and a second locking surface 521 formed on the movable insert wall 52 and interlockable with the first locking surface 436. The first locking surface 436 includes a plurality of first engaging teeth 241, while the second locking surface 521 includes a plurality of second engaging teeth 242. The locking mechanism 24 interlocks the connecting wall 43 and the movable insert wall 52, and fixes the movable insert wall 52 at a desired depth of the receiving groove 434. The elastic plate portion 437 is movable upward to disengage the first locking surface 436 from the second locking surface 521.

With reference to FIGS. 3, 5 and 6, the headrail holder 22 includes a holder seat 6 made of plastic, and a resilient headrail-clamp 7 connected to the holder seat 6 in proximity to a bottom end thereof. The holder seat 6 includes a mounting wall 61 detachably inserted into the mounting groove 45, and a headrail clamping wall 62 extending transversely from a top end of the mounting wall 61 in a direction away from the adjustment clamping seat 5. The mounting wall 61 has an abutment wall portion 611 abutting against the inner surface 421 of the stationary clamping wall 42, and two projecting wall portions 614 respectively abutting against the sidewalls 41. The abutment wall portion 611 has two opposite side parts 613, and an intermediate part 612 connected between the side parts 613. The projecting wall portions 614 respectively project from two opposite ends of the abutment wall portion 611, and are respectively inserted into the insert grooves 414 of the sidewalls 41. The headrail clamping wall 62 has an engaging groove 621 opening upward and distal from the mounting wall 61, and a headrail positioning space 622 adjacent to the mounting wall 61.

The resilient headrail-clamp 7 is made of a metal plate, but may be made of other material having a good structural strength. The resilient headrail-clamp 7 includes a fixed portion 71 fixed to a bottom end of the intermediate part 612 through a screw 221, a clamping portion 72 extending downwardly and curvedly from the fixed portion 71, and an operating portion 73 extending downwardly from the clamping portion 72 opposite to the fixed portion 71.

With reference to FIGS. 4, 5 and 7, to use the curtain bracket 2 of this embodiment, it is preferable that two curtain brackets 2 are used for hanging the curtain assembly 32 on the top end of the frame 31. However, for the sake of brevity, the use of only one curtain bracket 2 will be described hereinafter. During assembly, the movable insert wall 52 of the adjustment clamping seat 5 is first inserted into the receiving groove 434 of the connecting wall 43 of the main support seat 4 to complete the assembly of the hanging unit 21, after which the hanging unit 21 is hung on the top end of the frame 31 through the frame-clamping space 23. The distance between the movable clamping wall 51 and the stationary clamping wall 42 is then adjusted to shorten a width of the frame-clamping space 23. When the movable clamping surface 511 and the stationary clamping surface 422 respectively abut against inner and outer sides of the frame 31, the hanging unit 21 is stably hung on the top end of the frame 31.

With reference to FIGS. 4, 6 and 7, afterwards, the fixed portion 71 of the resilient headrail-clamp 7 is fixed to the bottom end of the intermediate part 612 of the holder seat 6 by using the screw 221 to complete the assembly of the headrail holder 22. The holder seat 6 is then mounted on the main support seat 4 by inserting the mounting wall 61 into the mounting groove 45. The assembly of the entire curtain bracket 2 is thus completed. Next, the hooked portion 325 of the outer sidewall 323 of the headrail 321 is engaged to the engaging groove 621, after which the headrail 321 is straightened such that the inner sidewall 323 thereof is disposed in the headrail positioning space 622. At this time, a junction of the inner sidewall 323 and the bottom wall 324 of the headrail 321 is supported by the clamping portion 72 of the resilient headrail-clamp 7, and the clamping portion 72 clamps the inner sidewall 323 of the headrail 321 against the headrail positioning space 622. Hence, a mounting operation of the curtain assembly 32 is completed.

To disassemble the curtain assembly 32 and the curtain bracket 2, the operating portion 73 of the resilient headrail-clamp 7 is first pulled downward to move the clamping portion 72 away from the headrail 321, after which the headrail 321 is moved slantingly so as to remove the inner sidewall 323 from the headrail positioning space 622 and to disengage the hooked portion 325 from the engaging groove 621. The curtain assembly 32 can thus be separated from the holder seat 6. Next, the elastic plate portion 437 is pulled upward to disengage the first locking surface 436 from the second locking surface 521, after which the adjustment clamping seat 5 is pulled in a direction away from the connecting wall 43 to prolong the distance between the movable clamping wall 51 and the stationary clamping wall 42 and to widen the width of the frame-clamping space 23. The curtain bracket 2 can be removed from the top end of the frame 31 at this time.

In sum, to use the curtain bracket 2 of this invention, the hanging unit 21 is first hung on the top end of the frame 31, the width of the frame-clamping space 23 is then adjusted to clamp the frame 31, followed by insertion of the mounting wall 61 of the headrail holder 22 into the mounting groove 45. The curtain assembly 32 can then be connected to the holder seat 6. Thus, it is not necessary to connect the curtain assembly 32 to the curtain bracket 2 prior to mounting of the curtain bracket 2 on the frame 31. Further, during assembly, the hanging unit 21 is quickly and stably mounted on the top end of the frame 31 by directly adjusting the width of the frame-clamping space 23 to clamp the frame 31, after which the headrail holder 22 is mounted on the hanging unit 21 and the curtain assembly 32 is connected to the headrail holder 22. Hence, in comparison with the conventional curtain bracket 13 (see FIG. 1), the curtain bracket 2 of the present invention can easily and quickly hung the curtain assembly 32 on the frame 31.
